BaCl2 + Na2SO4-----> 2NaCl + BaSO4(s)
net ionic equation- Ba+2 + SO4 -2 -----> BaSO4 (s)
Answer:
To understand the utility in sequence comparison and in the search for proteins that have a common evolutionary origin, you need to be clear about some concepts about how to evolve proteins. The idea that is accepted is that throughout the evolution some species are giving rise to new ones. Behind this is the genetic variation of organisms, that is, the evolution of genomes and their genes, as well as the proteins encoded by them.
Explanation:
Three ways can be distinguished by which genes evolve, and by proteins: mutation, duplication and shuffling of domains. When differences between homologous protein sequences are observed, these differences change to do with the way of life of the organism, an example of this, bacteria that live in hot springs at very high temperatures have proteins with a very high denaturation temperature, and these proteins are usually richer in cysteines. On the other hand, the fact that in positions of the sequences they remain unchanged (preserved positions), means that these have a special importance for the maintenance of the structure or function of the protein and its modification has not been tolerated throughout of evolution
Magnesium would be more reactive.
True
It’s true because models are based on real world problems to help grasp a understanding of the problem
To determine the cost of one sip of wine, we first calculate the cost of wine per unit volume. For this case, we need to convert the volume to milliliter for simplicity. We calculate the cost per volume as follows:
cost per volume = $ 278 / 24.5 fl oz ( 1 fl oz / 29.57 mL )
cost per volume = $0.38 / mL
To determine the cost of one sip, we multiply the volume of one sip to the cost per volume.
cost of one sip = $0.38/mL ( 2.0 mL ) = $0.77
